CVE-2026-20776: Denial of Service in Intel(R) PROSet/Wireless WiFi Software
Improper conditions check for some Intel(R) PROSet/Wireless WiFi Software within Ring 2: Device Drivers may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (high) impacts.
AI Analysis
Technical Summary
This vulnerability arises from improper conditions checks in Intel(R) PROSet/Wireless WiFi Software device drivers operating in Ring 2. It allows a denial of service (DoS) attack by a network adversary who does not require authentication or user interaction. The attack vector is adjacent network access with low complexity, potentially causing high impact on system availability. There is no impact on confidentiality or integrity. The CVSS 4.0 base score is 8.3, reflecting high severity. No remediation level or patch information is provided in the available data.
Potential Impact
The vulnerability can cause denial of service, resulting in high impact on system availability. There are no impacts on confidentiality or integrity. The attack can be performed by an unauthenticated attacker with adjacent network access and low complexity, without requiring user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation is currently documented.
